First Claim
1. A conveyor frame comprising:
- opposing side frames, each having a plurality of side frame apertures;
a plurality of cross members disposed between the opposing side frames and each having a cross member aperture defined by a flat inner wall and spaced juxtaposition to one of the side frame apertures;
a bolt comprising a shaft and a hook portion having an inner surface and a flat surface area extending a substantial distance across the inner surface, the hook portion mounted in one of the cross member apertures such that the flat surface of the hook portion is seated on the flat inner wall of the one of the cross member apertures;
the shaft extending through a juxtaposed one of the side frame apertures; and
a fastener mounted on the shaft to draw the side member and the cross member in an abutting relationship to clamp the cross member to the side member.

Abstract
A conveyor comprises parallel side frames provided with a plurality of apertures and C-shaped cross members provided with apertures in the side walls disposed in juxtaposition to apertures in the side frames. The cross member apertures are each defined by a flat inner wall. The cross members are fastened to the side frames by hook-bolts having a hook portion extending through the side wall apertures and a shaft extending to a juxtaposed aperture in the side frame and provided with a nut and washer to secure the bolt in the side frame. The hook portion of the bolt is provided with a flat surface extending a substantial distance across the inner surface of the hook portion of the bolt to provide a load bearing contact area with the inner wall of the side member aperture. The cross members have tabs extending outwardly from each end which are inserted into complementary apertures in the side frames. The resulting bolted conveyor frame construction ensures frame alignment under heavy loads.
